    • setMappingFile

      public void setMappingFile(File mappingfile)
      PUBLIC: Sets the file from which the reader will read the RDF-to-topic map mapping definition. The syntax will be assumed to be "RDF/XML".

    • setMappingFile

      public void setMappingFile(File mappingfile, String syntax)
      PUBLIC: Sets the file from which the reader will read the RDF-to-topic map mapping definition.
      Parameters:
      syntax - The RDF syntax to use. Possible values are "RDF/XML", "N3", "N-TRIPLE". If the value is null it defaults to "RDF/XML".

      PUBLIC: Sets the URL from which the reader will read the RDF-to-topic map mapping definition.
      Parameters:
      syntax - The RDF syntax to use. Possible values are "RDF/XML", "N3", "N-TRIPLE". If the value is null it defaults to "RDF/XML".

    • setGenerateNames

      public void setGenerateNames(boolean generate_names)
      PUBLIC: Controls whether or not to automatically generate names for nameless topics from their subject indicators.
      Since:
      2.0.5

    • setDuplicateSuppression

      public void setDuplicateSuppression(boolean duplicate_suppression)
      PUBLIC: Tells the reader whether or not to perform duplicate suppression at the end of the import. The default is to not do it.
      Since:

      PUBLIC: Tells the reader whether or not to stop when errors are found in the mapping. The default is to stop.
      Since:
      2.1

    • setBaseAddress

      public void setBaseAddress(LocatorIF baseAddress)
      PUBLIC: Sets the base address of the topic maps retrieved from the source.

    • read

      public TopicMapIF read() throws IOException
      Description copied from interface: TopicMapReaderIF
      PUBLIC: Reads the next topic map available from some implicit, implementation dependent source.

      A topic map source may contain multiple topic maps. The read method returns the next topic map that is available from that source. null is returned when there are no more topic maps available. In a sense this is iterator-like behaviour.

      Specified by:
      read in interface TopicMapReaderIF
      Returns:
      The next topic map read from the source; an object implementing TopicMapIF. null is returned when there are no more topic maps available from the source.
      Throws:
      IOException - Thrown if reading the source fails.

    • readAll

      public Collection readAll() throws IOException
      Description copied from interface: TopicMapReaderIF
      PUBLIC: Reads all the topic map available from some implicit, implementation dependent source.

      A topic map source may contain multiple topic maps. The readAll method returns a collection contain all the topic maps available from the source.

      Specified by:
      readAll in interface TopicMapReaderIF
      Returns:
      A collection containing all the topic maps read from the source; objects implementing TopicMapIF.
      Throws:
      IOException - Thrown if reading the source fails.

    • importInto

      public void importInto(TopicMapIF topicmap) throws IOException
      Description copied from interface: TopicMapReaderIF
      PUBLIC: Imports an implicitly designated topic map into the given topic map.
      Specified by:
      importInto in interface TopicMapReaderIF
      Parameters:
      topicmap - The topic map into which the import will be done; an object implementing TopicMapIF.
      Throws:
      IOException

    • setAdditionalProperties
